“…Readings were obtained between the hours of 1300 and 1600 since the exposure rate meter has a maximum response to environmental radiation within these hours [1]. The radiation exposure reading in all the Oil Spill sites were converted to absorbed dose using the conversion factor shown in equation 1, [15].…”

“…Nigeria is blessed with a huge deposit of oil resources in the Niger Delta with an estimated crude oil reserves of approximately 22.5 billion barrels [1]. Advances in industrial development and human living standards, the demand for energy throughout the world is ever increasing [2].…”

“…Its arable terrain and water resources can sustain a wide variety of crops, lumbar and agricultural trees and more species of freshwater fisheries than any other wetland in West Africa [4]. Exploration has also resulted in various environmental problems such as oil spills, which have had a major impact on the Niger Delta ecosystem of the oil-producing areas [1]. Delta State is a part of the Niger Delta and is classified as containing the world's third largest wetland, with the most extensive freshwater swamp forest and rich biological diversity [13].The area is one of the highest in oil and gas production onshore of Niger Delta with about 172 oil wells with 10 flow stations and 14 flare stack sites.…”

Study of the terrestrial Background Ionizing Radiation levels of selected Oil Spill Communities of Delta State, Nigeria have been carried out using Digilert 200 and Radalert 100 nuclear radiation monitor and a geographical positioning system (Garmin GPSMAP 76S). The exposure rates of the five communities ranges from 0.016 to 0.030 at Jones Creek, 0.014 to 0.034 at Opuwade Community, 0.015 to 0.037 at Okpare community, 0.007 to 0.029 at OtuJeremi community and 0.011to 0.040 at Otor-Edo community. The obtained mean exposures rates were higher than ICRP standard limit of 0.013. The absorbed dose rates calculated ranged from 139.2 to 261 (Jones Creek), 121.8 to 259.8 nGyh-1 (Opuwade Community), 130.5 to 321.9 nGyh-1 (Okpare community), 60.9 to 252.3 nGyh-1 (OtuJeremi community) and 95.9 to 348 nGyh-1 (Otor-Edo community). The estimated annual effective dose equivalent varies from 0.21 to 0.40 , 0.19 to 0.45 , 0.20 to 0.49 , 0.09 to 0.39 and 0.15 to 0.53 for Jones Creek, Opuwade Community, Okpare community, Otu Jeremi community and Otor-Edo community respectively while the excess lifetime cancer risk calculated for Jones Creek varies from (0.75 to 1.40) x 10-3, Opuwade community (0.65 to 1.59 )×, Okpare community (0.70 to 1.73 ) x , OtuJeremi community (0.33 to 1.35)× and Otor-Edo community (0.51 to 1.87)×. All the mean values of absorbed dose, annual effective dose and excess lifetime cancer risk exceeded their recommended safe values. The results obtained in this work may not constitute any immediate health risk to the residents of the selected oil spill communities but long term exposure in the area may lead to detrimental health risks.
